Abstract
The 20 essential oils extracted from different angiospermic plants, Agele marmelos (L) Correa, Ageratum conyzoides L., Allium sativus,. Ammomum subulatum Roxb. Anethum graveolens L., Caesuliaaxillaris Roxb,. Callistemon lanceolatus DC., Chenopodium ambrosioides L., Cinnamomumcamphara L., Cinnamomumcamphara L., Citrus reticulate Blanc,. Citrus sinensis L., Curcuma longa L. Koenig, Cymbopogan citrates DC., Elettaria cardamomum Maton., Eucalyptus citriodera Hook., Eupatorium cannabinum L., Foeniculum vulgare Mill., Trachyspermum ammi L., Zingiber officinale were tested to screen against Aspergillus flavus. Among them, the maximum percent mycelial inhibition was recorded with Chenopodium and Trachyspermum oils. Further physico-chemical properties of these two essential oils were identified by using GLC. MIC of Chenopodium and Trachyspermum essential oils at 100-400 ppm actively against A. flavus (post harvest fungus) which proved to be fungistatic and fungicidal effects as control mechanism. It would be developed to be potential as post-harvest fumigants.
